## Problem
Learning data, patterns, and Q-values were not being persisted correctly due to
database fragmentation across three separate files:
- .agentic-qe/memory.db (MCP writes)
- .agentic-qe/data/swarm-memory.db (CLI reads - wrong path)
- .agentic-qe/agentdb.db (created but never used)
## Solution
Unified ALL persistence to single database via SwarmMemoryManager singleton.
### Core Persistence Fixes
- CLI commands now use getSharedMemoryManager() instead of hardcoded paths
- learn status queries learning_experiences, patterns, q_values tables directly
- patterns list queries patterns table instead of memory_entries
- Removed agentDB default path from BaseAgent and agent factory
- database-init no longer creates separate agentdb.db
- Added queryRaw() method to SwarmMemoryManager for direct table queries
